摘　　要：文章提出一种改进的电网分区无功优化迭代模型和算法,将上下层电网进行更为清晰的划分,利用界面节点的电压和功率进行上下层迭代来求得全网的无功优化解。并且给出了迭代算法的收敛判据。通过在某地区电网的应用表明,分区迭代算法在优化质量、收敛可靠性和时间方面都比全网整体优化有优势。The improved reactive power optimization algorithm and model considering power grid partitioning is presented in this paper.The upper and lower power grid is classified more clearly;reactive optimization solution of the whole systems is obtained by the voltage and power of interface nodes through upper and lower interation.And the convergence criterion of iterative algorithm is also given.At last,it is shown through application of the proposed algorithm at a certain regional power grid that partition iteration is much better than the whole grid in the aspects of optimization quality,convergence reliability and time.
